Complete agreement, Joel.
What follows may look better in proportional fonts.
With a single slash we can wrap as follows
1234567 9012345
Goes to…
1234567 \
9012345
…and unwrapping is easy.
However, if I want to manually wrap the line with indentation
The quick brown fox jumps over the lazy dog
...going to…
The quick brown fox\
jumps over the lazy dog
…I am going to unfold as…
The quick brown fox jumps over the lazy dog
Conversely, if I resolve this second case by stripping leading spaces I get…
The quick brown foxjumps over the lazy dog
So I have to fold as…
The quick brown fox \
jumps over the lazy dog
But this causes the first case to unfold as
1234567 9012345
…i.e., with missing spaces.
This is what caused the use of the second slash so…
1234567 \
\ 9012345
…and…
The quick brown fox\
\ jumps over the lazy dog
So, my point is, if and only if we do not care about these “spaces on the fold”
cases, we can operate with a single slash.
Cheers,
Adrian

Hey.
I’ve been having this discussion with Kent off-line, but thought it should come
to the list.
I don’t think it is a good idea to have two approaches. While it would be
relatively easy to code for both approaches, it seems to add a degree of
confusion if both have to be handled by the same code (consider deciding
whether leading space characters are to be retained or not, something that can
only be decided when the first non-space character is found), or by having
different code for the two different cases.
It doesn’t seem to me that both cases are needed. We can pick one or the other.
A single slash has been used to wrap long lines in editors and shells for
decades at this point.
and yeah whatever it is one method seems better than two.
And *if* we want to allow manual folding so that indents can be made to make
the document more human-readable then we have to use a leading ‘\’ on
continuation lines to show which spaces should be stripped and which retained.

Adrian

I had a chat with the tools team recently and, in the course of things, it was
implied
that the double backslash approach we have now was both surprising and
non-intuitive.
This got me thinking that we may have thrown the proverbial baby out with the
bathwater.
That is, currently we have a header that reads:
NOTE: '\\' line wrapping per BCP XX (RFC XXXX)
So why not *also* support a header that reads (note the singe slash):
NOTE: '\' line wrapping per BCP XX (RFC XXXX)
Whereby this second form only supports the folded line continuing on column 1
(no indents).
Thoughts?
